Levallois-Perret to Paris: 6.8 km Northwest

Levallois-Perret is a dense, compact commune in the Hauts-de-Seine department, immediately northwest of Paris proper.

Distance: 6.8 km (4.2 miles) from central Paris (measured to Notre-Dame/Point Zéro).
Travel time: ~15-20 minutes by Metro (Line 3), 10-15 minutes by car/taxi off-peak, 30+ minutes in rush hour.
Border: Shares boundary with Paris 17th arrondissement.

Essentially an inner suburb—integrated into Paris's urban fabric, served by Métro, bus, and Vélib'. Residential, commercial, and growing tech sector. Former industrial base (Citroën factories) redeveloped.

Not to be confused with the broader "Petite Couronne" inner ring—Levallois is one of the closest independent communes to Paris center.
